Kedu ka e si emepụta resin phenol formaldehyde?

Bakelite bụ resin phenolic.Phenolic resin (PF) bụ ụdị ngwaahịa rọba arụ ọrụ.Ngwa ngwa nke phenolic resin mmepụta bụ tumadi phenol na aldehyde, na phenol na formaldehyde na-ejikarị eme ihe.A na-eme ha polymerized site na mmeghachi omume condensation n'okpuru catalysis nke acid, isi na ihe ndị ọzọ.E nwere ụdị abụọ nke mmepụta mmepụta ihe: usoro akọrọ na usoro mmiri.

N'okpuru omume nke dị iche iche catalysts, phenol na aldehyde nwere ike ịmepụta ụdị abụọ nke phenolic resins: otu bụ thermoplastic phenolic resin, nke ọzọ bụ thermosetting phenolic resin.Enwere ike ịgwọ nke mbụ n'ime ihe mgbochi site na ịgbakwunye onye na-agwọ ọrịa na kpo oku, ebe enwere ike ịgwọ nke ikpeazụ n'ime ihe mgbochi site na ikpo ọkụ na-agbakwunyeghị onye na-agwọ ọrịa.

Thermoplastic phenolic resin na thermosetting phenolic resin nwere ike iji naanị site na netwọk mgbanwe emebere site na ọgwụgwọ.Usoro ọgwụgwọ bụ ịga n'ihu nke ọdịdị polycondensation na ịmepụta ngwaahịa ọdịdị.Usoro a dị iche na agbaze na ọgwụgwọ nke thermoplastics izugbe.Ma usoro anụ ahụ na nke kemịkal enweghị ike ịgbanwe.

Enwere ike ịkpụzi resin phenolic n'otu ụzọ ahụ na thermoplastic.PF maka ịkpụzi injectionchọrọ ezigbo mmiri mmiri, enwere ike ịkpụzi ya n'okpuru nrụgide injection dị ala, isi ike dị elu, ike na-agba ọsọ ngwa ngwa, ezigbo gloss elu nke akụkụ plastik, mwepu dị mfe, na enweghị mmetọ ebu.Agbanyeghị, ịkpụzi injection nwekwara ọghọm ya.Dịka ọmụmaatụ, agbaze na-ejedebe site na ụdị ihe nkpuchi, n'ihi ya, ọ dịghị mma iji ntinye ihe ndị ọzọ na-emepụta akụkụ plastik.Enweghị ike ịmegharị ọnụ ụzọ ámá na ọwa buru ibu mgbe a gwọchara ya, naanị enwere ike ịtụfu ya.

Na okwu, thermoplastic phenolic resin nwere ike ịmepụta site na igwe na-akpụzi injection nkịtị, mana a na-achịkwa ọnọdụ usoro ahụ nke ọma.Thermosetting phenolic resin ga-abụ nke igwe na-akpụzi injection pụrụ iche maka resin phenolic, na ebu ahụ na-anabatakwa usoro nhazi pụrụ iche.
